The released radioactive materials drifted in the air as a plume according to the wind at that time. Although the amount of radioactive materials released changed from moment to moment, and the flow was greatly affected by weather and wind direction at the time of release, most (about 80% in the case of cesium-137) flowed out to sea …

Six years after the Fukushima nuclear reactor disaster in Japan, radioactive material is leaching into the Pacific Ocean from an unexpected place. Some of the highest levels of radioactive cesium ...

Cesium-134, while much shorter-lived, will persist for a number of years. The chemical properties of radioactive cesium are similar to those of non-radioactive cesium and naturally occurring potassium and sodium, which are abundant in seawater. So all these end up in the same tissues, particularly muscle, of fish and other marine organisms.

Claim: The first "radioactive salmon" attributed to the Fukushima nuclear disaster have been found in British Columbia, Canada, posing a risk to human health.

In March 2011, the Fukushima Daiichi Nuclear Power Plant was damaged by a powerful earthquake and tsunami, causing nearby lakes to be contaminated with radioactive cesium-137. Although the ...

The authorities have used ALPS and other systems to remove some of the most hazardous isotopes, like cesium-137 and strontium-90. But there's a radioactive …

According to the Japanese news service, NHK, a recent sample also contained 1.1 million times the legal level of radioactive cesium-137. Studies from previous releases of nuclear material in the Irish, Kara and Barents Seas, as well as in the Pacific Ocean, show that such radioactive material does travel with ocean currents, is …

That marked nearly a 15-fold increase from readings five days earlier, and exceeded Japan's provisional emergency standard of 60 becquerels per liter for cesium radiation levels in drinking water.

To understand the dynamics of accident-derived radioactive cesium (137Cs) in stem wood that had a substantial amount of heartwood at the time of the Fukushima Dai-ichi Nuclear Power Plant accident, the radial and vertical distributions of 137Cs activity concentration in stem wood of Japanese cedar (Cryptomeria japonica), cypress …

In April 2012 we carried out a 1-year hematological study on a population of wild Japanese monkeys inhabiting the forest area of Fukushima City. This area is located 70 km from the Fukushima ...

By David Pacchioli | May 2, 2013 » The Fukushima nuclear disaster delivered an unprecedented amount of radioactivity into the sea over a relatively brief …

In particular, the data released show that the content of Cs-137, a radioactive element that is a common byproduct in nuclear reactors, is 180 times that of the standard maximum stipulated in Japan's food safety law. Screenshot of Tokyo Electric Power Company's report on the radioactive content in fish in the harbor of the Fukushima …

This paper focuses on an overview of radioactive cesium 137 (quasi-Cs137 included Cs134) contamination of freshwater fish in Fukushima and eastern Japan based on the data published by the ...

The plant operator, known as TEPCO, analyzed a black rockfish in May that was found to contain levels of radioactive cesium that were 180 times over Japan's regulatory limit, The Guardian reported ...

The plant operator, known as TEPCO, analyzed a black rockfish in May that was found to contain levels of radioactive cesium that were 180 times over Japan's regulatory limit, The Guardian reported. The fish was caught near drainage outlets at the plant, where three nuclear reactors melted down in March 2011 during a tsunami.

On February 21, 2021, a Tokyo Electric Power Company employee measures radiation outside its Fukushima Daiichi nuclear power plant, devastated a decade ago by an earthquake. Japan's planned ...

The destruction of the Fukushima Daiichi nuclear power plant in March 2011, caused by an earthquake and subsequent tsunami, resulted in massive radioactive contamination of the Japanese mainland. In November 2011, the Japanese Science Ministry reported that long-lived radioactive cesium had contaminated 11,580 square miles (30,000 sq km) of the ...

Measurements off the coast of Japan in 2011 identified radioactive cesium from the Fukushima incident throughout the food web, with higher levels in organisms closer to shore. Since the second quarter of 2015, cesium levels in all organisms have been well below Japan's safety limits for human consumption, but the isotope has persisted. ...

Radioactive Cesium: This is the other element that's been in the news here in Japan, especially making headlines with regard to spinach contamination. Cesium isotopes from nuclear fission generally come in two flavours: Cesium-134 and Cesium-137. The most common of the two is Cesium-137.

1. Introduction. The Tohoku earthquake and subsequent major tsunami off the Pacific coast of Japan on 11 March 2011 triggered the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident, which resulted in the release of large quantities of radioactive materials to the air and ocean (Buesseler et al., 2011, Chino et al., 2011, Yasunari et al., …

The radioactive fallout included many volatile radioisotopes, including iodine-131, cesium-134, cesium-137, and xenon-133. Of these, cesium-137 comprises the majority of the long-term ...

In March 2011, in association with the Great Tohoku earthquake and resultant tsunami, there was an accident at the Fukushima Daiichi nuclear power plant on the east coast of Japan. This accident released the radionuclides cesium 134Cs and 137Cs into the ocean next to the plant, exposing marine life to radioactive materials.

September 2021 Update. Today FDA is deactivating Import Alert #99-33 (IA) that has targeted certain food products from Japanese prefectures (Japan's equivalent of a U.S. state) located near the ...

A black rockfish caught near Fukushima by fishermen had caesium levels five times above the government's permitted levels. Radioactive cesium five times above permitted levels in Japan has been detected in black rockfish caught in northeastern Fukushima Prefecture, according to a Feb. 22 announcement by a local fishing association.

For the first time since 2019, fish contaminated with high levels of radioactive cesium have been caught off the coast of the Fukushima Prefecture in Japan on Feb. 22, according to local public broadcaster NHK.
